Sweden's first ever female Prime Minister has resigned just hours after she was appointed.
Instead, parliament voted for a budget drawn-up by the opposition which includes the anti-immigrant far right.
" I have told the speaker that I wish to resign, " Ms Andersson told reporters.
" There is a constitutional practice that a coalition government should resign when one party quits, " The Social Democrat said on Wednesday. " I don't want to lead a government whose legitimacy will be questioned.
The speaker of parliament said he would contact party leaders on The Next move.
Ms Andersson was elected as Prime Minister earlier on Wednesday because under Swedish law, she only needed a majority of MPs not to vote against her.
A hundred years after Swedish women were given the vote, the 54-year-old Social Democrat leader was given a Standing Ovation by sections of the parliament, or Riksdag.
Her election at The Head of a minority government followed an 11th-hour deal with the opposition Left Party , in exchange for higher pensions for many Swedes. She also secured the support of coalition partner The Greens .
Of the 349 members of the Riksdag, 174 voted against her. But on top of the 117 MPs who backed Ms Andersson, a further 57 abstained, giving her victory by a single vote.
A former junior swimming champion from the university city of Uppsala, she began her political career in 1996 as political adviser to then-Prime Minister Goran Persson . She has spent The Past seven years as Finance Minister .
The complexities of Swedish politics mean we can't assume we've seen The Last of her, though. If there's another prime ministerial vote, Ms Andersson will probably get voted in again. This is because the Green Party has promised to support her, despite quitting as a formal coalition partner. But she'd end up in a vulnerable position at the helm of a fragile minority government, and would still have to stick to The Right -wing budget already voted on by parliament.
What all this political chaos has underlined is just how divided Swedish politics is right now. We'll have to wait and see whether voters break the deadlock with a significant shift to The Right or The Left at next year's elections.You may also be interested in:
